Marantz 2238B full service

[@kevinyoungM14EBR]

I appreciate your video, thank you! My father purchased a 2238B brand new in the late 70's and allowed me and a good friend to use it to power our armature mobile DJ side gig, we put that receiver through hell and it never let us down. It was retired to bubble wrap in a box in the mid 80's and languished there until the Chinese Flu hit, that's when I dug it out so it could be professionally cleaned & serviced by a reputable shop. A few incandescent bulbs, resistors and capacitors were replaced before it was fired up for daily use in my small listening / bed room. I connected two different sets of ADS bookshelf speakers (570/2 & 780/2), a Technics turn table (SL-1500) and a Technics CD player (SL-PD8) with an external DAC (Schiit Modi+). This combination of vintage gear sounds really good to my ears, so good that I will never consider replacing it with any modern gear.

Thanks for sharing your story... sounds like you had a great set up!

[@leszekalbin4097]

Great presentation and it came from "heaven" because yesterday I bought a beautiful Marantz 2238B black! Best regards👍🏻

[@craigm.9070]

Thank you for your time sir! You extend the life of great pieces of stereo equipment a lot of us grew up with...they won't make any more that's for sure. Enjoy your weekend.

[@dwayneanderson71]

It's pretty cool how I get mezmarized watching you fix stereo equipment. I have always wanted to learn how to do it but never did. I just took stuff apart and never put it back together lol

[@TrevorsBench]

What a surprise, another screwup in a Marantz service manual! Good job Joe, thanks for sharing

[@bertramlefarge69]

Can i suggest using a door wedge on that rotating table when you're unscrewing the side panels, my OCD is kicking in lol Great channel btw :)

[@stusax1]

Nice unit, good job, Thanx joe.

Glad you like it!

great job! thanks for sharing

I am lucky to own this exact same amplifier from legendary Marantz. It effortlessly runs two Bose B2 Bass speakers at 200 watts 4 ohms on bridge mode. It has never blown a fuse on me.

Joe im a big fan from Portugal!

[@VintageAudioFever]

Ah!!! thank you Sir

[@richardjohnson7638]

This is inspiring DIY content! Thank you for the instruction on safely discharging the capacitors - - subbed. 🤘🏼😎🤘🏼

[@geraldmosley2195]

Hey, very informative video, thank you. When you did your bias check, it was hard to see what pot you said was left or right because you had the meter in the way, can't see how you discharged your filter cap.

[@jharp53]

Great explanation on repairs.

Gran descubrimiento el error de J722 & J724 - J722 & J728!!! 🎉🎉🎉 Voy por un Marantz 2230 espero no tener sorpresas! Gracias por el video!

[@emilagaev8764]

Good afternoon. Errors in the diagram sometimes appear. The main thing is not to panic!!

[@chuckmatses6803]

Hello, I can't find a video that shows the actual removal of the old stereo and Dolby lamps. Mine are stuck in there, maybe glued, not sure. Any ideas? Greetings from Boxford, MA

[@allanpickel2439]

Enjoyed your video!

[@DjMarkGuzman]

Hey Joe That turntable you use for units you work on did you build it your self or buy it and where did you get it?

[@MatthewLasky-cg7vi]

I have a humming when I turn to phono output. No phono attached. Any ideas?

[@VintageAudioFever]

Hi Matt My experience with humming would be a bad soldering...or perhaps a bad capacitor that is to ground...I would start with that.

[@tuantrd]

That’s funny the manuals for 2252b is right pin (728) the 2238b and 2252b is exactly the same design, you forgot to remove the corrosive glue under the metal clips on the thermals transistor that will eat through the plastic and caused a major shortage to the output transistors

[@sirsuse]

Come on 1000!!. 🎉

[@Asian_Connection]

Are you supposed to determine is there is a cause for the low voltage before adjusting it?

[@Daltondoubledeuce]

Hi Joe, where do you get that round spin platform you have the receiver on? Thx!

[@VintageAudioFever]

Hi...the turntable i made out of an end tabletop i had, and i went to Princess Auto and bought turntable bearings... Slape some paint and voila!!! Under 10$

[@Daltondoubledeuce]

@@VintageAudioFever thank you!

[@darellhands1602]

How would you tweak the fm tuner if it was out of whack ?

[@VintageAudioFever]

Can you laborate a bit...what do you mean by out of wack? You saying the indicator is not on the right channel?

[@darellhands1602]

Seems it needs a tweaking. Stations are hard to come in

[@markchapman7326]

Hi ! Nice video ! Have a question : (not fluent english sorry) I changed the shaft of my 2235B selector switch. Since no left channel (except tape 1 using his own button) some people told me baffles are not align together anymore. How can I align them what are the reference on baffles helping me to align them all together please ? thanks for helping me sir. Canada salute you :D !

[@VintageAudioFever]

Hi Mark...from what I gather...you change the shaft of the potentiometer?

[@markchapman7326]

@@VintageAudioFever No idea what is a potentiometer but the SELECTOR switch (AM FM PHONO TAPE 2 AUX) I changed the shaft since old one was broken. Since my first comment to you I did replace it - I did re align all waffles - so now after a long 3-4 hours (I'm not technician and cant real a scheme of service manual ) I succeed to align all waffles so new switch works. Learning what each of the 4 waffles role were was a challenge but I understood each role of each waffle ... But at the end it's a success :)

[@VintageAudioFever]

Glad you were able to repair yourself...Good Job!!!

[@markchapman7326]

@@VintageAudioFever I’m glad too. Now since some capacitors and so must be bad shape the unit will go to a repair shop. You read technical manual ?

[@VintageAudioFever]

Yes I read 'em....
